Building simulation software helps deliver office with highest-ever BREEAM score

14 October, 2007

IES Consulting worked closely with consulting engineers King Shaw Associates (KSA) to provide independent validation of the design for the building that has achieved the highest-ever BREEAM score. The Green Office project at Thorpe Park, Leeds, has achieved a BREEAM score of 87.55%. The design was validated before construction began.

A changing climate for thermal mass

14 October, 2007

Exploiting thermal mass within a building can eliminate the need for air conditioning. Tom De Saulles explains how.

Priva helps Dublin school go greener

14 October, 2007

Monitored energy results for the first year of operation of the Archbishop Ryan School in Dublin indicate that its energy performance is twice as good as that of a school constructed to meet the good-practice targets outlined in CIBSE Guide F. Energy consumption was monitored by the Priva control system installed by Temperature Control Systems to optimise the operation of lighting and heating systems in response to the benefits of passive solar gain, daylight and natural ventilation.

Keith Melton reflects on the thinking that is needed to deliver sustainable buildings.

Natural ventilation by design

14 October, 2007

Natural-ventilation systems that can respond fully to ever-changing outdoor conditions are much more effective than systems with limited response capability. Richard Arnott explains.

Lighting management built in at start in City refurbishment

GSHP provides central services for Cornish development

14 October, 2007

Two ground-source heat pumps provide heating and hot water for a development of 12 apartments and two penthouses on the Clipper Cove development at Praa Sands on the south coast of Cornwall.

Rainwater recycling

14 October, 2007

DAB Pumps’ Aquaprof collects rainwater and uses it for purposes such as flushing toilets, washing machines, garden irrigation and vehicle washing. This water is delivered at mains pressure. If there is not enough stored rain water, the Aquaprof switches to an integral back-up tank containing mains water.

The role of pumps in delivering energy savings

13 October, 2007

There is very little to be gain by improving the efficiency of pumps to reduce their energy consumption. Much more can be saved — about half — using speed control and the better design of systems, as John Veness explains.

Countering the fire risk

13 October, 2007

It is over 60 years since a death was recorded in the UK in a building with a working sprinkler system. Glynn Williams cuts through the complexities of using pumps to protect against the risk of fire.

Wilo shows the way to reduce pumping costs

13 October, 2007

Replacing pumps in 12 plantrooms at Derriford Hospital in Plymouth with equivalent pumps from Wilo’s energy-efficient range will reduce energy consumption by £70 000 a year — a useful dent on the electricity bill of over £1 million a year.

Grundfos energy project enters its third phase

13 October, 2007

Grundfos is moving into the third phase of its project to increase awareness of how using efficient circulators can significantly reduce carbon-dioxide emissions. The project started in 2005 with the launch of the world’s first A-rated domestic circulator — the Alpha Pro.

How Grundfos aids pump selection

13 October, 2007

To help customers decide which pumps would best suit their needs, regardless of the application, Grundfos provides a range of selection tools —which have become industry standards. These aids are constantly reviewed and updated to keep them relevant.

Delivering energy-efficient pumps

13 October, 2007

Designing systems with duty and standby pumps that can both meet maximum demand is must not efficient. Wayne Rose explores other approaches.

Smedegaard enhances the efficiency of circulators

13 October, 2007

Smedegaard has developed a range of electronic energy-saving circulators that use up to 60% less energy than a standard pump.

The world’s most efficient circulator?

13 October, 2007

The Wilo-Stratos ECO high-efficiency pump has been given an 'excellent' rating by the German consumers’ association Stiftung Warentest. It came top in tests as the best in energy efficiency and ratio of price to performance compared to all other small circulating pumps.

On a mission to save energy

13 October, 2007

Over a hundred HVAC drives with native BACnet capability have been installed in the new Blackburn Hospital to control water pumps and motors for air-handling units. One of the key benefits was a significant time saving during commissioning.

More refrigerant bans possible, says government

The government could tighten up the rules that restrict the use of global warming refrigerant gases including speeding up phase-out programmes and introducing new bans, according to a spokesman from the Department for Environment, Food and Rural Affairs (DEFRA).

Baxi research suggests schools strongly support heat decarbonisation

A survey conducted by Baxi of 200 state school estates managers, consultant engineers and M&E contractors has found that while enthusiasm for Net Zero and support for low carbon heating systems in schools is thriving, persistent barriers remain.
